RELATED APPLICATION

The present application claims the benefit and priority of U.S. Provisional Patent Application No. 62/517,352, filed Jun. 9, 2017, which is hereby incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure generally relates to packages for medical devices, and more particularly, to packages for urinary catheters. Even more particularly, the present disclosure relates to packages that are configured to contain a hydrophilic catheter and a hydration liquid for activating the hydrophilic catheter.

BACKGROUND

It is desirable for medical devices that are inserted into the body to have a lubricated or lubricious outer surface to facilitate insertion into and/or removal of the medical device from the body. Such devices may include, for example, urinary catheters, endoscopes, cardiovascular catheters, syringes, vascular stents, etc. Such medical devices may have a hydrophilic coating or layer disposed on an outer surface thereof. Hydrophilic coatings are becoming the preferred method of providing lubricious surfaces because of their high lubricity and ease of use. Hydrophilic coatings become slippery or lubricous when wetted with a hydration medium, such as saline or liquid or vapor water. The hydrated lubricous hydrophilic coating eases insertion and removal of the device, which can result in minimizing soft tissue damage and reducing overall discomfort during use of the medical device.

When a hydrophilically coated medical device is used, the hydrophilic coating is hydrated with a hydration medium prior to use to activate the hydrophilic coating. For example, the user may immerse or otherwise contact the hydrophilic coating with a hydration liquid to hydrate or activate the coating. It is also becoming quite common to provide a package that includes the medical device and hydration liquid within the cavity of the package. In one type of package, the hydration liquid may be loose within the package and in contact with the hydrophilic medical device during storage and distribution of the package. In another type of package, the medical device and an openable sachet or pouch that contains the hydration liquid may be located within the package. In this second type of package the user bursts open the sachet within the package just prior to use. After the sachet is burst open, the hydration liquid is released and is loose within the package wherein it contacts and hydrates the hydrophilic medical device.

In packages that contain a hydration liquid, the hydration liquid is either initially loose within the package or becomes loose after being released from a sachet. Because these packages include loose hydration liquid at the time of opening the package, there is a risk of hydration liquid spillage upon opening the package and removal of the medical device from the package. Such spillage may cause a mess, which can require clean up. In some instances, the hydration liquid may include additives that can undesirably stain the clothes of the user.

Therefore, there remains a need for improved medical device packages for containing a medical device and a fluid, wherein the package assists in reducing the risk of fluid spillage.

FIGS. 1-4 a and 4 b-4 d, illustrate top peel open packages wherein the packages are initially opened along the top and then along the sides of the package. FIGS. 1-3 illustrate a four side sealed package that includes two sheets sealed together. This package may be opened by peeling apart the two sheets at the top seal and then peeling along the side seals. FIGS. 4b-4c illustrated a flow-wrap package made from a single sheet having a fin seal and two end seals wherein the sides of the package a defined by fold lines. This package may be opened by peeling of the top seal and then tearing along the side fold lines. Each of these packages may include a first opening-stop located in the first side of the package and a second opening-stop located in the second side of the package. In a four side sealed package, the opening-stops may be located in the respective side seal zones. In a flow-wrap package, the opening-stops may be located adjacent to the respective side fold lines of the package. The first and second opening-stops limiting opening of the first and second sides of the package.

FIGS. 1-3 illustrate a medical device package 10 a for containing a medical device 12 a. The package 10 a includes a front sheet 14 a and a back sheet 15 a (FIGS. 2 and 3). The front sheet 14 a includes an inner surface 16 a facing the back sheet 15 a, an outer surface 17 a facing the ambient atmosphere, a top edge 18 a, bottom edge 19 a and opposed first and second side edges 20 a and 21 a. Referring to FIGS. 2 and 3, the back sheet 15 a includes an inner surface 22 a facing the front sheet 14 a, an outer surface (not shown) facing the ambient atmosphere, a top edge 23 a, bottom edge (not shown) and opposed first and second side edges 24 a and 25 a.

The front sheet 14 a and back sheet 15 a may be made from a liquid and gas impermeable material. For example, the front and back sheets 14 a and 15 a may be made from a polymer film and/or a metal film. In one embodiment, the material may be a polymer/metal laminate, such as a polymer/aluminum laminate.

The front sheet 14 a and back sheet 15 a may be sealed to each other to define a cavity for holding the medical device 36 a. In one embodiment, the front sheet 14 a and back sheet 15 a may be sealed to each other to form a gas tight cavity. In the illustrated embodiment, the front sheet 14a and back sheet 15 a are sealed to each other by a peripheral seal 26 a. The peripheral seal 26 a may be a peelable seal that may be a heat seal, an adhesive seal or any other suitable peelable seal that allows the front sheet 14 a to be separated from the back sheet 15 a when the sheets are peeled apart during use. The peripheral seal 26 a may include a top seal zone 27 a, bottom seal zone 28 a, and opposed first and second side seal zones 29 a and 30 a. The peripheral seal 26 a is preferably a continuous seal. The first side seal zone 29 a of the peripheral seal 26 a may extend along at least a portion of the first side edges 20 a and 24 a of the front and back sheets 14 a and 15 a, and the second side seal zone 30 a of the peripheral seal 26 a may extend along the second side edges 21 a and 25 a of the front and back sheets 14 a and 15 a. The first and second side seal zones 29 a and 30 a may be at or spaced from the first and second side edges of the front and back sheets. The bottom seal zone 28 a of the peripheral seal 26 a may be at or spaced from the bottom edges of the front and back sheets 14 a and 15 a. The top seal zone 27 a of the peripheral seal 26 a may be spaced inwardly from the top edges 18 a and 23 a of the front and back sheets 14 a and 15 a such that the top edges 18 a and 23 a are free and not attached to each other. The top seal zone 27 a may be in a linear configuration or non-liner configuration. For example, the top seal zone 27 a may have a pointed shape, such as the chevron shape shown, or it may have a rounded chevron shape. Furthermore, the top sheet 14 a and/or the bottom sheet 15 a may, optionally, include a finger hole 33 a to aid in grasping the sheets.

The package 10 a also may include a first opening-stop, such as first peel-stop 31 a, located in the first side seal zone 29 a of the peripheral seal 26 a. The package 10 a also may include a second-opening-stop, such as second peel-stop 32 a, located in the second side seal zone 30 a of the peripheral seal 26 a. The first and second peel-stops 31 a and 32 a limit peeling of the first and second side seal zones 29 a and 30 a of the peripheral seal 26 a. In one embodiment, the first and second peel-stops 31 a and 32 a may prevent further peeling of the first and second side seal zones 29 a and 30 a of the peripheral seal. In another embodiment, the first and second peel-stops 31 a and 32 a may provide a tactile feel that alerts the user that the package has been sufficiently opened so that the user knows to stop peeling.

In use, the user opens the package 10 a by grasping the front and back sheets 14 a and 15 a at or near the respective top edge 18 a and 23 a. The user may insert their finger through the finger hole 33 a, if one is present. The user then pulls the front and back sheets 14 a and 15 a apart to initiate separation of the sheets. As the user pulls sheets 14 a and 15 a apart, the sheets peel apart at the top seal zone 27 a of the peripheral seal 26 a and then they peel apart along side seal zones 29 a and 30 a. As the user continues to pull the sheets 14 a and 15 a apart, the sheets peel apart along the side seal zones 29 a and 30 a until reaching the peel-stops 31 a and 32 a. When the peel-stops 31 a and 32 a are reached, further peeling may be prevented and/or the peel-stops may provide a tactile feel that alerts the user to stop peeling. As shown in FIG. 3, at that point, a selected segment of the medical device is exposed and the user may grasp the medical device and remove it from the package.

The first and second opening or peel-stops may have a variety of different configurations. For example, peel-stops 31 a and 32 a may be configured so that more force is required to peel the peel-stop portions of the peripheral seal 26 a than other portions of the seal. In one embodiment, the first and second peel-stops 31 a and 32 a may comprise widened seal portions or seal portions of greater area than the adjacent portions, as shown in FIGS. 1 and 2. Optionally, the peel-stops 31 a and 32 a may include opening interruption elements, such as peel interrupt elements 34 a and 35 a. The peel interruption elements 34 a and 35 a may include cuts or perforations through the front sheet 14 a and/or the back sheet 15 a in the peel-stops 31 a and 32 a. The cuts or perforations may be die-cuts or laser-cuts and they may be any variety of shapes and sizes. For example, the peel interruption elements 34 a and 35 a may be generally J-shape, generally V-shape or generally hook-shape. Furthermore, the peel-stops 31 a and 32 a may be positioned so that the package opens to expose a selected portion of the medical device, such as the distal end of a catheter. In one embodiment, the peel-stops are positioned closer to the top seal zone of the peripheral seal than the bottom seal zone of the peripheral seal. In another embodiment, the peel-stops may be positioned such that only the distal end 36 a of the medical device is exposed when the package is opened.

In the embodiments shown FIGS. 1-3, the package 10 a is illustrated as containing a catheter as the medical device 12 a. Also, the peel-stops 31 a and 32 a are positioned closer to the top seal zone 27 a of the peripheral seal 26 a so that when the package 10 a is opened, the distal end 36 a of the catheter is exposed. In another embodiment, the opening-stops or peel-stops may be positioned so that the distal third or less of the catheter is exposed. In the illustrated embodiment the catheter includes a gripping aid 36 a′ and the peel-stops may be positioned so that only the portion of the catheter that includes the gripping aid 36′ may be exposed. The peel-stops 31 a and 32 a also include J-shaped peel interruption elements 34 a and 35 a. When the user peels the front and back sheets 14 a and 15 a along side seal zones 29 a and 30 a, the front and back sheets 14 a and 15 a peel apart along the side seal zones 29 a and 30 a until the peel-stops 31 a and 32 a are reached. When the peel-stops 31 a and 32 a are reached, the peel interruption elements 34 a and 35 a tear in the J-shaped pattern preventing further peeling along the side seal zones 29 a and 30 a, as shown in FIG. 3. Additionally, the tearing of peel interruption elements 34 a and 35 a may provide the user with a tactile feel to let the user know to stop peeling. If the user continues to peel the front and back sheets apart, the peel interruption elements 34 a and 35 a may direct the force toward the center of the sheets which will prevent further peeling or make the sheets harder to peel apart.

When the package 10 a includes a liquid within the cavity, such as a hydration liquid, the peel-stops may also define pockets, wells, or indents 37 a within the cavity (FIG. 1). When the package 10 a is opened, the liquid may pool in the pockets 37 a to prevent or reduce spillage. For example, when the package 10 a includes a catheter and hydration liquid for hydrating a hydrophilic surface of the catheter, if the opened package is tilted, the liquid may pool or be collected in pockets 37 a and be prevented from spilling out of the package. Furthermore, the front sheet 14 a and/or the back sheet 15 a may, optionally, include a channel 40 a that extends length wise along the sheet. The channel 40 a may be for collecting hydration liquid. When the front and back sheets are made from a polymer/metal laminate, the channels may be formed by pressing or stamping the sheets so as to have a desired shape, such as one or more channels. The sheets may also be formed to have indents or wells.

FIGS. 5 and 6 illustrate further embodiments of packages 50 a and 50 b which are four-sided sealed, top side peel open packages similar to that shown in FIG. 1. Packages 50 a and 50 b each include a front sheet and back sheet (not shown) that are sealed to each other by a peripheral seal 52 a, 52 b to define a cavity for containing a medical device, such as a catheter with a hydrophilic surface, and hydration liquid. The peripheral seal includes a top seal zone 54 a, 54 b, a bottom seal zone 56 a, 56 b, a first side seal zone 58 a, 58 b and a second side seal zone 60 a, 60 b. The top edges of the front and back sheets above the top seal zone 54 a, 54 b are unsealed so that the user may pull the top of the front and back sheets apart to peel open the top seal zone 54 a, 54 b, thereby initiating opening of the package. Optionally, the front and/or back sheets may include a finger hole 62 a, 62 b to assist the user in grasping the sheets.

The first side seal zone 58 a, 58 b and second side seal zone 60 a, 60 b may include a plurality of opposed wide seal portions or projections 62 a, 62 b that project into the cavity of the package and opposed narrow seal portions 64 a, 64 b. The wide seal portions 62 a, 62 b may be peel-stops. The wide and narrow seal portions 62 a, 62 b and 64 a, 64 b define pockets, wells, or indents 66 a, 66 b in the side seal zones within the cavity. When the packages 50 a and 50 b are opened, the liquid may pool in the pockets 66 a, 66 b to prevent or reduce spillage. For example, if the open package is tilted, the liquid may pool or be collected in pockets 66 a, 66 b and be prevented from spilling out of the package. In the illustrated embodiment, the wide seal portions or projections 62 a, 62 b may be at an angle to the rest of the side seal zones. The projections 62 a, 62 b also may define a V-shaped pocket with the narrow seal portions 64 a, 64 b. Furthermore, the projections 62 a, 62 b may also include peel interruptions elements, such as any of those described above. As illustrated in FIG. 6, the package may include more pockets by increasing the number of alternating wide and narrow seal portions.

Turning to FIG. 4a , there is shown another embodiment of a package 41 a having a generally rectangular shape, which may be a square. Package 41 a includes a front sheet and a back sheet (not shown) that are sealed to each other by a peripheral seal 42 a to define a cavity for containing a medical device. The package may contain a catheter with a hydrophilic surface and hydration liquid. The peripheral seal 42 a is a five side seal that includes a top seal zone 43 a, upper seal zones 44 a along two sides of the package and lower seal zones 45 a along the other two sides of the package. The top seal zone is spaced from one of the corners 46 a of the package 41 a such that a portion 47 a, 47 a′ of each of the front and back sheets are not attached to each other. The package 41 a also includes peels-stops 48 a which may be located anywhere along the upper seal zones 44 a. In the illustrated embodiment, the peel-stops 48 a are located between the upper seal zones 44 a and the lower seal zones 45 a. The peel-stops 48 a may, optionally, include peel interruption elements 49 a, such as any of the peel interruption elements described above.

To open the package 41 a, the corner portions 47 a, 47 a′ of the front and back sheets above the top seal zone 43 a are peeled apart to unsealed the top seal zone 43 a. The user continues to pull the front and back sheets apart to peel open side seal zones 44 a until the peel-stops 48 a are reached. The user then removes the medical device. In the embodiment, the medical device may be a catheter or other device that is coiled or otherwise folded to fit in the package.

Turning to FIGS. 4b-4c , there is shown another embodiment of a medical device package 10 b. Package 10 b is a flow-wrap package made from a single sheet of material. Package 10 b is formed by folding the single sheet at fold line 16 b and fold line 18 b. The sheet is then sealed at or near the top edge 20 b of the sheet by a top seal 22 b. The sheet is sealed at or near the bottom edge 24 b by a bottom seal 25 b. The side edges of the sheet are also sealed at a fin seal 28 b (FIG. 4b ). The formed package 10 a includes a front panel 12b (FIG. 4b ) and a rear panel 14 b (FIG. 4c ) defined between fold lines 16 b and 18 b. The fold lines 16 b and 18 b define the side edges of the package. The fold lines 16 b and 18 b may be cut above the top seal 22 b so as to define two flaps 30 b and 32 b. Flaps 30 b and 32 b may be grasped by the user and pulled apart to peel open the top seal 22 b and to tear the package along fold lines 16 b and 18 b.

The package 10 b also may include a first opening-stop 34 b and a second opening-stop 36 b, wherein each opening-stop is located at or near a respective side edge 16 b and 18 b of the package 10 b. The opening-stops also may be at or adjacent to the top seal. The first and second opening-stops 34 b and 36 b limit tearing of the package along the side edges of the package defined by fold lines 16 b and 36 b. In one embodiment, the first opening-stop 34 b and second opening-stop 36 b may prevent further tearing of the first and second side edges of the package. In another embodiment, the first opening-stop 34 b and second opening-stop 36 b may provide a tactile feel that alerts the user that the package has been sufficiently opened so that the user knows to stop tearing the package. The first opening-stop 34 b and second opening-stop 36 b may be any of those described above. For example, the first opening-stop 34 b and second opening-stop 36 b maybe a sealed portion wherein a portion of the front panel 12 b and back panel 14 b are sealed together. Optionally, the first opening-stop 34 b and second opening-stop 36 b may include opening interruption elements 38 b, such as J-shaped, generally V-shaped or generally hook-shape cuts or perforations, as described above.

In use, the user opens the package 10 b by grasping flaps 30 b and 32 b. The user may insert their finger through the finger hole, if one is present. The user then pulls the flaps 30 b and 32 b apart to separate top seal 22 b. As the user continues to pulls flaps 30 b and 32 b apart, the package tears along the side edges defined by fold lines 16 b and 18 b until reaching the opening-stops 34 b and 36 b. When the opening-stops 34 b and 36 b are reached, further opening may be prevented and/or the opening-stops may provide a tactile feel that alerts the user to stop opening the package.

FIGS. 7-9 c illustrate a medical device package 10 of the present disclosure.

When package 10 is a four-sided sealed package, the front sheet and back sheet (not shown) forming the package may be sealed to each other about their peripheries to define an inner cavity that holds the medical device and, optionally, a hydration liquid. For example, package 10 may include a continuous four-sided peripheral seal that extends along the top edge 14, side edges 18 and 20 and bottom edge 16. When package 10 is a flow-wrap package, the body 12 of the package may be generally tubular and include the top seal 22, bottom seal 24 and a fin seal (not shown) at the rear of the body 12. Furthermore, the side edges 18 and 20 may be formed or defined by folds of the flow-wrap package.

The material from which package 10 is formed may be a multilayered flexible laminate film(s). Such films may include a weldable inner layer and a protective middle or outer layer. For example, the laminate films may include a polymeric inner layer, a metallic middle layer and a polymeric outer layer. The multilayered laminate film may also include a directional tear element that directs the film to tear in a desired direction. In one example, the directional tear element may direct the laminate film to tear in a substantially linear manner. In one embodiment, the directional tear element may be a controlled directional tear laminate film that may include one or more layers of oriented polymer which controls the direction or the tearing of the film. For example, the controlled directional tear film may direct the film to tear in a substantially linear line. In another embodiment, the directional tear element may be a directional tear tape that is superimposed over at least a portion of the film and directs the film to tear in a desired direction.

Package 10 may also include a tear initiator or tear initiation element 26 associated with a front wall 25 of the body 12. In the illustrated embodiment, the tear initiator 26 includes a tear initiation line 27, such as a slit or perforation in the package material. The tear initiation line 27 may form a tear initiation flap or tongue 28 in the laminate film. The tear initiator tab 28 may be located spaced from the top seal 14 and is preferably positioned between opposed sided edges 18 and 20. In the illustrated embodiment, the tear initiator tab 28 is centered between the opposed side edges, but it may also be closer to one side edge or the other. The tear initiator 26 also includes a gripping portion 30 that the users grips and pulls to initiate tearing of the package material to form an opening in the package. In the illustrated embodiment, the gripping portion is shown as a pull tab 30 that has an adhesive portion 32 which is attached to the body 12 of the package 10 and an unattached portion, such a free end 34. The adhesive portion 32 is adhered to the package and overlies the tear initiation flap 28.

Referring to FIGS. 8 and 9A, to open package 10, the user grasps the free end 34 of the pull tab 30 and pulls. As the pull tab 30 is pulled, the adhesive portion 32 of the pull tab 30 remains adhered to the tear initiation flap 28, but releases from the package material surrounding the flap 28. As the user continues to pull the pull tab 30, the tear initiation flap 28 initiates longitudinal tearing of the front wall 25 of the body 12 of the package 10, thereby forming a longitudinal opening 38 that is parallel or substantially parallel to the one or both of the side edges 18 and 20 and extends from the initial location of the tear initiation flap 28 toward the bottom edge 16 of the body 12 of the package 10. In one embodiment, the package includes a directional tear element that directs the package material to form a substantially linear tear. The user may pull the pull tab 30 until a desired sized opening 38 is created in the front wall 25 of the package. Additionally, the bottom seal 24 may serve as a stop that stops the tearing of the material of the package.

Once the desired opening 38 is formed, the user may reach into the package through opening 38 to remove the catheter. As shown in FIGS. 9B and 9C, the inner cavity of the package defines a space for containing fluid 40 within the package 10 and the narrow, longitudinal opening 38 reduces the risk of accidental spilling of the fluid 40 from the package 10. Additionally, opposed side pocket-like areas 42 and 44 are defined between the opening 38 and the front wall 25 and back wall 48 of package 10 wherein the fluid 40 may flow and collect in such pocket areas 42 and 44 when the package is turned to one side or the other, as illustrated in FIG. 9C. The ability for the fluid 40 to pool in the pocket areas 42 and 44 also assist in reducing accidental spillage of the fluid when the package 10 is turned to one side or the other.
